The Impact of Health Tools on Your Daily Wellness

ECG captures single-lead heart-rhythm readings while continuous SpO2 monitors oxygen saturation and body composition measures body metrics, and advanced sleep tracking produces a sleep score tied to recorded stages.

Trackable vitals and a sleep score make trends easy to share with a clinician or to adjust training plans. Wearers with smaller wrists should consider the 44 mm case size, which can feel bulky and reduce nighttime comfort.

Refining Runs with Advanced Run Coaching

Auto Workout Tracking, built-in GPS, Advanced Run Coaching and VO2 max estimation pair with live coaching connectivity to record pace, route, and performance metrics while on the move.

If you often run without your phone, confirm cellular activation and GPS lock before long outings to avoid losing live data mid-session. Continuous GPS and cellular use will shorten operational runtime, so plan for shorter phone-free workouts or carry a backup device.
